Answer / wasif arshad

in simple words it is a very small air handling unit and
suspended above the false ceiling. A small blower throws
air which when strikes with the coil becomes hot or cool as
the case may be.

CFM (cubic feet per minute) can be calculated by the help
of cfm meter. it simply consists of a fan and a display
unit. When the fan is taken in front of diffuser it rotates
with a fix speed depending on the speed of air. Fan is
connected with a switch which produces fix no of impules
depending on its speed. Hence these impulses are sent to
the display unit at which these impulese appear in the form
of cfm

Answer / sag

The Area of the Diffusser is taken in to consideration and
velocity of the air. by this we can calculate the CFM

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
